The DSTDEVP function calculates the standard deviation of an entire population, provided the data set is from a sample taken from a population with a normal distribution.


=DSTDEVP(database, field, criteria)

database The range of cells containing the database or list that you want to perform the calculation on.
field The specific column or field from which you want to calculate the standard deviation.
criteria The conditions or criteria that determine which records to include in the calculation. This argument is optional.
placeholder1 Description of the cell range or column name in the data source


When you find yourself in need of determining the standard deviation for an entire population based on a sample, DSTDEVP in Excel has your back. This function proves handy in scenarios where you possess a subset of data from a larger population that adheres to a normal distribution model, making it a suitable choice for statistical analyses that aim to characterize a broader group based on a smaller sample slice. By leveraging DSTDEVP, you can efficiently compute the population standard deviation without overlooking valuable insights that the whole dataset can offer. To make the most of DSTDEVP, specify the data range to consider, pinpoint the respective field containing the values to analyze, and optionally establish criteria for filtering out specific records. Tailoring these parameters ensures that the standard deviation computation aligns with your analytical objectives. DSTDEVP stands as a reliable tool for obtaining a holistic view of population variability based on a sample, sharpening your statistical acumen as you delve into the intricacies of data analysis.


Suppose you have a dataset stored in cells A1:A20 and want to calculate the standard deviation of the entire population from the 'Sales' field in the dataset. The formula using DSTDEVP would be: =DSTDEVP(A1:A20, 'Sales')

If you wish to include certain criteria in the calculation, such as filtering by 'Region' equals 'North', you can modify the formula: =DSTDEVP(A1:B20, 'Sales', 'Region=North')


When should I use the DSTDEVP function in Excel?

You should use the DSTDEVP function when you have a dataset representing a sample drawn from a larger population that follows a normal distribution, and you aim to calculate the standard deviation for the entire population based on this sample.

What role does the 'criteria' argument play in the DSTDEVP function?

The 'criteria' argument in the DSTDEVP function allows you to specify conditions that determine which records from the database are included in the standard deviation calculation. This feature enables tailored analysis by filtering out specific data points.

Can I use the DSTDEVP function for datasets that do not follow a normal distribution?

The DSTDEVP function is specifically designed for datasets derived from populations with a normal distribution. For datasets that deviate from this distribution pattern, alternative functions or statistical methods may be more appropriate for calculating measures of dispersion.
